Mainline Linux tree for various devices, only for fun :)

At the moment everything assumes a full linear mapping of the various exception stacks. Adding guard pages to the cpu entry area mapping of the exception stacks will break that assumption. As a preparatory step convert both the real storage and the effective mapping in the cpu entry area from character arrays to structures. To ensure that both arrays have the same ordering and the same size of the individual stacks fill the members with a macro. The guard size is the only difference between the two resulting structures. For now both have guard size 0 until the preparation of all usage sites is done. Provide a couple of helper macros which are used in the following conversions.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
